Abstract

The invention relates to a switching device, in particular for a voltage limiting device, which has a first fixed switching contact 14 which is electrically connected to a first device terminal 8, a second fixed switching contact 15 which is electrically connected to a second device terminal 9, and a movable switching contact 16. The invention also relates to a voltage limiting device which has such a switching device 5. The first and second fixed switching contacts 14, 15 of the switching device are arranged next to one another in such a way that their contact surfaces 14A, 15A point in the same direction. The movable switching contact 16 can be moved between a closed position in which the first and second fixed switching contacts 14, 15 are electrically connected to one another, and an open position in which the first and second fixed switching contacts 14, 15 are separated from one another. The first and second fixed switching contacts 14, 15 and the movable switching contact 16 form an arrangement of electrical conductors which are arranged substantially parallel to one another. At least one of the fixed switching contacts 14, 15 has an elongated contact surface which extends in the direction A of current flow. Electrodynamic forces act on the fixed conductors 14, 15 and the movable conductor 16, which are directed in such a way that the conductors attract each other, i.e., the switching contacts tend to close.
